Wouldn't it be nice to be in a 9-5 environment again, I remember those days!
5 and 9 meaning something different to us these days; 99.999% uptime, which equates to 5 minutes downtime a year. Before we started using replication we use to do a UVBackup to a disk that was then moved to a NAS server to keep a months worth of disk images on-line. This happened every hour on the hour. Obviously we could never be sure of the referential integrity of the database but we have programs that report on missing transactions etc and I can't remember the last time we had to use a backup anyway (apart from testing them every two days). ________________________________ From: [EMAIL PROTECTED] on behalf of John Hester Sent: Fri 10/12/2004 23:18 To: [EMAIL PROTECTED] Subject: Re: [U2] UniVerse Backup/Resizing Questions Dave Schexnayder wrote: > 2) Backups.

I've only done OS level backups, so I can't objectively compare them to uvbackup, but this has worked fine for us since migrating to UV in '96. We do frequent restores of various archived files for accounting report requests. Fortunately we're a 9-5 operation, so I have a window at the end of the day where I can be sure no updates are happening on the filesystem. If you can't prevent writes during your backup, and you don't have a mirrored filesystem you can break apart, there are a number of backup solutions that can handle open files. St. Bernard and Unitrends Backup Professional are a couple. St. Bernard works in conjunction with the backup software of your choice, and Backup Professional has built-in open file management. It's my understanding that all files are saved in a consistent state by monitoring the filesystem at the OS level and caching any disk writes until the particular file is backed up. This gives you a backup of your filesystem as it was at a specific point in time. Of course you still have to start your backup at a point in time when no transactions are in mid-stream if you want to be able to restore everyting to a consistent state. -John -- John Hester System & Network Administrator Momentum Group Inc.
